Seq extensions: add trySkip

[knocte]

This way it is an alternative to Seq.skip: same but
non-partial function (that doesn't throw exceptions),
following same approach as tryHeadTail[1].

@gdziadkiewicz hey do you mind helping me upgrade paket (and paket deps) from v6 to v8? I'm not a paket expert, I just replaced net6.0 with net8.0 and upgraded paket version (see last commit), but seems that is not enough (see build failure).

[gdziadkiewicz]

Hi @knocte , no problem, I will take a look tomorrow morning :)

[gdziadkiewicz]

Hi @knocte , let's keep the update and the trySkip separate. I prepared the update in #224 .

[knocte]

Lovely thanks; sounds good, I'll rebase as soon as 224 lands.

@knocte I'm working on making the Fable tests work after my changes, sorry for the wait

[gdziadkiewicz]

@knocte merged the other PR

@gdziadkiewicz hey, thanks! Rebased.

Now, it seems CI is failing because, even though your PR upgraded general things to .NET8.x(&F#v8.x), FSharp.Core seems to be still locked to 4.x.

How can I upgrade FSharp.Core to v8.x? I assume that I gotta change manually the version in packet.dependencies file, but I guess I gotta run something else after that change, to make it propagate to packet.lock file?

Thanks.

(BTW the PR can already be reviewed in case you have feedback, and I will address it too next time I update the PR, cheers.)

Mmm, changing manually both files seemed to work. If this is ok lmk and I'll squash latest commit to get this ready to be merged.
